The smallest, most capable 350 W
power supply of its kind.
Designed for applications using the latest logic families, the outputs’ turn-on and
turn-off are monotonic. Turn-on transition
is less than 200 ms. The highly effective
N +1 configuration lets the main output
from the NMX power supply work in
conjunction with the main output of any
similar power supply of the same voltage.
This provides expanded capability, great
flexibility in OEM design, and fail-safe
redundancy.

SPECIFICATIONS: ALL MODELS
OPTIONS:
INPUT
AC Input: 90-264 Vac continuous range, 47 to 63 Hz. Internally fused for 7 A.
Power Factor: 0.99 typical at full load. Meets EN61000-3-2.
Inrush: Cold start AC current is less than 30 A at 115 Vac and 60 A at 230 Vac. Limited by
thermistor.
Brownout Protection: Holds regulation to 85 Vac.
Holdup Time: 20 ms minimum after removal of power at full load.
Efficiency: 75% typical.
AC Power Fail: Provides TTL “0” 5 ms before output voltage goes out of regulation band upon
loss of ac power.
Option “E”, Euro Style Connector: Provides input and auxiliary output connections accepting
14 to 24 AWG wire.
Option “F”, Fan/Cover Assembly: Cover with integral ball-bearing fan provides proper cool
ing to achieve full ratings at 50°C ambient temperature. 1.85” dimension increases to 3.08”.
Option “V”, Fan/Cover Assembly: Low profile, end venting cover with integral ball-bearing fan.
1.85” dimension increases to 2.50”, and 8.05” dimension increases to 9.40”.
OUTPUT
Adjustability: Outputs #1 and 2 user adjustable ±5% minimum. Output #3 tracks #2; initial
accuracy ±4%. Output #4 user adjustable ±5% minimum, or +5% only if voltage is 5.2 V.
Line & Load Reg: Outputs #1, 2, and 4 hold ±1% over AC input range and 0 to 100% load
change. Output #3 requires 20% minimum load on outputs #2 and 3 to hold ±4%.
Ripple & Noise: Less than 1% p-p or 100 mV, whichever is greater.
Remote Sense (Output #1): Compensates for 250 mV total line drop. Open sense lead
protection. (See Redundancy, below)
Temperature Coefficient (Outputs #1, 2, and 4): 0.02% per degree C.
Stability: 0.1% over 8 hours after 30 minutes warm-up.
Transient Response (Outputs #1, 2, and 4): Output voltage returns to within 1% in less than
500 µs for a 50% load change. Peak transient does not exceed 5%.
Overload Protection: All outputs are protected against overload and short circuit. Automatic
recovery upon removal of fault.
Overvoltage Protection (Outputs #1 and 2): Protects load against power supply induced
overvoltage. Trip point is factory set so that output voltage cannot exceed 136% of nominal.
Peak Output Current: Dual current ratings define continuous and peak currents. The peak current
shown can be delivered for a maximum period of 30 seconds.
Remote Inhibit: Contact closure to the negative sense line or a TTL level “0” turns off DC
outputs.
DC Power Good: Provides a TTL “1” open collector when output #1 is above 4.6 V nominal.
Redundancy: External OR-ing diodes and forced current sharing on output #1 provide “N+1”
capability. Remote sense (+S) compensates for additional 0.6 V diode voltage drop. When
the current sharing terminal is connected between units, current sharing remains within
10% of the unit’s full output current rating.
Reverse Voltage: Protected against reverse voltage up to supply current rating.
ENVIRONMENTAL
Thermal Protection: Shuts down power supply if overheated. Automatic recovery.
Temperature Range: 0° to 50°C at full ratings.
Safety Agencies: Most models are approved to UL1950; CSA 22.2 #234; IEC 950 and TÜV
EN60950, Class 1 SELV., CE 72/23/EEC/93/68EEC (low voltage directive)..
Conducted RFI: Meets FCC Part 15, Subpart J, Class A; EN55022 Class B; CISPR 22 Class B.
Output Isolation: Isolated from ground 50 Vdc.
Cooling: 30 CFM required to achieve full ratings.
Consult factory for other available options.
